Answer:
I will attach a picture, but I need you to attach a screenshot so I can solve it.
Step-by-step explanation:
But here:
In 9, the differences between two consecutive terms are
6-3,12-6,24-12...
3,6,12...
Which is not same. So it is not is arithmetic progression .
In 10. the differences are
Which is not same, so it is not in arithmetic progression too .
Answer:
x = 53
y = 30
Step-by-step explanation:
Step(I):-
Given equations are
x -2y =-7 ...(I)
5x-9y =-5 ..(ii)
The matrix form AX = B
The determinant
By using Cramer's Rule
Δ₁ =
The determinant is Δ₁ = -9 X -7 - (10 ) = 53
x = Δ₁ / Δ
x = 53
The determinant
Δ₂ =
Δ₂ = -5 +35
y = Δ₂/Δ = 30
